mdocml: In man(1) mode without -a, stop searching after the first manual

[schwarze@mdocml.bsd.lv]

Log Message:
-----------
In man(1) mode without -a, stop searching after the first manual tree
that contained at least one match in order to not prefer mdoc(1) from
ports over mdoc(7).  As a bonus, this results in a speedup.
